Hello everyone.
I was doing some testing at work in Houdini 19.5 with POP and DOP stuff. I have uploaded a example file with basic geo, where I would like to swap low res with high res geometry.

The problem is, that the particles generated in "DOP network" are not showing up in "Transform pieces" node, even when I cached them.

I can see the particles when I select "DOP import", but once I select "Transform pieces", only particles generated in "POP network" are displayed. I did pack the geometry, created "name" attribute and transferred it, but nothing really seems to work.
Particles generated in DOP network, have their "pieceXXX" names, but when I click DOP import, only few of them have the name attribute, although I see plenty of them in the viewport.

What am I doing wrong?
Thank you in advance!

Hi Bobsen,

I'm not sure "Transform Pieces" will work this way.

The spawner only ever puts out one single name attribute string: "piece0".
It's always the same and does not increment.

After sim, you have a bunch of template points with name attribs, but those are also "piece0" for each one.

I suppose that's why "Transform Pieces" can't handle the setup. It will be looking for an individual name attrib
for each template point AND for each GEO so it can match those.

I am not sure that's the way to go for a spawn setup. At least I don't know how.
Smarter people here certainly will.

But at least that might explain why it's not working as is.
Hope this helps anway.

Yeah. I only got particles created in POP node. Transform pieces usually goes together with DOP import, and I thought that I can feed DOP with POP and cache DOP output. Well, seems like that is not the way.
Thanks a lot!
